Abstract: The Commission received correspondence from William M. Hannay, counsel for Safety Glazing Certification Council, requesting that the Commission initiate rulemaking to replace the current testing procedures for glazing materials codified at 16 CFR 1201.4 with those contained in ANSI Z97.1, "American National Standard for Safety Glazing Materials Used in Building-Safety Performance Specifications and Methods of Test." The request was docketed as Petition CP 12-3, under the Consumer Product Safety Act (CPSA). On August 23, 2012, the Commission voted unanimously to approve publication of a notice in the Federal Register to solicit public comments on the petition. The notice was published in the Federal Register on August 30, 2012. The comment period closed on October 29, 2012. CPSC staff reviewed the submitted comments and sent a briefing package to the Commission on April 3, 2013. The Commission voted unanimously (3-0) on April 9, 2013 to grant the petition.
